Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed March 21, 1912. Serial No. 685,217.

To all whom it may concern.-

Be it known that I, ARTHUR PONTON, a citizen of the United States,residing .at Murdock, in the county of Douglas, State of Illinois, haveinvented certain new and useful Improvements in Bed-Spring Tighteners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in bed spring tighteners, andmore particularly to one for stretching fabric springs.

The invention has for its object to provide a stretcher which may beconveniently operated for tightening the springs to restore the same totheir normal condition.

With this and other objects in view, the invention consists in certainnovel features of construction, combination and arrangement of parts aswill be hereinafter fully described and claimed.

in the drawing: Figure 1 is a plan view of the device. Fig. 2 is a sideelevation of the same. Fig. 3 is a sectional view on line 3-3 of Fig. 1.Fig. a is a top plan view showing the device in one of its stretchedpositions. Fig. 5 is a bottom plan View of the device. Fig. 6 is adetailed perspective view of one of the rod connecting castings.

Referring to the drawing, the numeral 1 designates the side bars of theframe, said bars being held. in spaced parallel relation by metallicstraps 2. The ends of the side bars are formed with slots 3 foradjustably supporting the opposite ends of the end bars 4. The wirefabric forming the spring 5 is secured, in any suitable manner to theend bars.

Formed centrally upon the opposite faces of the bars t are castings 6,said castings being formed with spaced cars 7 for pivotally receivingthe outer ends of the rods 8, the inner ends of said rods being threadedfor engagement by the turn-buckle 9. Similar castings 10 are mountedupon the opposing faces of the end bars 4, and upon opposite sides ofthe castings 6, said castings serving to pivotally connect the outerends of the brace arms 11 to the end bars. The brace arms have theirinner ends formed with angular extensions 12 having perforations 13formed therein and adapted to register with the perforations 14 formedin the rods 8.

The rods 8 are gradually curved downwardly at their inner .ends toaccommodate the sagging of the spring 5 near its center due to the factthat the weight of the body is greater at this point upon the mattressand springs than at any other.

It ofttimes occurs that when a person sleeps constantly upon one side ofthe mattress, that portion of the springs directly thereunder willnaturally stretch more, and to overcome this, the brace arms 11 may beso adjusted that one of the perforations 13 therein will register withone of the perforations let of the rods 8 and in advance of the angularextension 12 of the oppositely disposed arm 11, and at which timeclamping bolts are passed through the registered perforations of thedifferent parts, thus holding the adjusted end bar in diagonal relationto the side bars, as clearly shown in Fig. t of the drawing.

From this construction, it will be seen that upon manipulation of theturnbuckle 9, the spring 5 will be effectually stretched through themedium of the rods 8 and at a time when the end bars 4 are disposedtransversely or diagonally with the side bars 1, and as the occasion mayrequire.

What is claimed is:

A bed spring tightener comprisin a pair of side bars having slots formedin their ends, end bars supported in said slots, a fabric spring havingits ends secured to the end bars, rods having their outer ends pivotallyconnected to the end bars, a turn buckle connecting the inner ends ofsaid rods, means for shifting the end bars in diagonal relation to theside bars, said means consisting of a pair of arms pivotally connectedat their outer ends to each end bar and having their inner ends adaptedto be adjustably connected to said rods, and adapted to have their endsadjustably connected to the op posite'sides of said rods and in diagonalrelation, thereby stretching one side edge of the spring more than theother upon opera tion of the turn buckle.

In testimony whereof, I atiix my signature, in presence of twowitnesses.

ARTHUR PONTON.
